Answer 1

Answer:

Earth consists of three main layers: the crust, the mantle, and the core (Figure 3.4).  The core accounts for almost half of Earth’s radius, but it amounts to only 16.1% of Earth’s volume.  Most of Earth’s volume (82.5%) is its mantle, and only a small fraction (1.4%) is its crust.
